RE: Finally Figured out my problem
Do you have the rest set so the center of the arrow is 13/16" from the riser???
Does your arrow perfectly bisect the berger hole???
Is your nock and rest set so your arrow is dead level???
Have you set your Idler lean???
Nock an arrow as if you were going to shoot and draw back like you normally would....While trying to keep form, look up at the idler wheel and see if the string is tracking perfectly straight down the idler wheel....If not you are torguing the bow or you need to set Idler lean Or a combo of both.
The Switchback does seem to like weaker spined arrows....I am shooting 29" Maxima 250's and they shoot terriffic.
